TORONTO, ONTARIO -- (Marketwired) -- 04/30/13 -- Lago Dourado Minerals Ltd. (TSX VENTURE: LDM), (the "Company") has completed the first diamond drill hole at the Arrastro Hills South East porphyry target at its flagship 100%-owned Juruena Project located in Mato Grosso, Brazil. Hole JRND068 was drilled vertically to a depth of 480m to test a strong muscovite alteration signature that corresponded with a major crosscutting fault structure and a deep seated IP anomaly. Drill core for the hole is being split and logged on site and will be shipped for fire assaying later this week.

Photographs of drill core from the top 200m of the hole are available at www.lagodourado.com (under Projects - Juruena - Drill Core Photos) and a schematic with the key geochemical and geophysical data, alteration data and drill hole locations at Arrastro Hills is provided in Figure A (http://media3.marketwire.com/docs/ldmfiga430.pdf). A brief geological summary of the hole is provided below:

-- 0 - 31m - Saprolite and transition zone from saprolite to fresh rock.-- 31 - 176m - Strongly altered fine-grained volcanic that is intruded by magnetite-rich fine to medium grain felsic and mafic porphyries. Mineralisation consists predominantly of finely disseminated sulfides and sulfide-filled fractures and veins. Sulfide-carbonate veins associated with minor brecciation are also present. Pyrite is the most dominant sulfide mineral observed and occurs in combination with chalcopyrite in places.-- 176 - 480m - Moderately altered fine-grained volcanics with minor felsic porphyries. Mineralisation below 176m is only weakly developed and consists of disseminated sulfides and thin sulfide-filled fractures.



Drilling productivity has significantly improved compared to the start of the year due to the easing of the wet season and Arrastro Hills South East being much more accessible than the central part of Arrastro Hills. The next hole planned at Arrastro Hills South East (JRND069) is approximately 500m east of JRND068 and will target a phengite-rich zone that corresponds with an IP anomaly and broad Au-Cu soil anomaly. The presence of phengite is indicative of a higher temperature part of the system that may represent an exposed part of a porphyry system. A study conducted by the MDRU found a strong association between phengite and gold mineralization at known mineralized zones elsewhere at Juruena, including the Crentes, Tomate and Uiliam zones, which are located proximal to Arrastro Hills South East.
